Given numbers are 248,578,521,921,810

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 248,578,521,921,810 is 4642807160520.

Find LCM of 248,578,521,921,810 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 3 x 124 x 289 x 521 x 307 x 135 = 4642807160520

Therefore, the lowest common multiple of 248,578,521,921,810 is 4642807160520.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

248 x 578 x 521 x 921 x 810 = 55713685926240

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

248 : 1, 2, 4, 8, 31, 62, 124, 248

578 : 1, 2, 17, 34, 289, 578

521 : 1, 521

921 : 1, 3, 307, 921

810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 248,578,521,921,810, is 1.

Now, the common factors can be found like this.

248:2x 2x 2x 31

578:2x 17x 17

521:521

921:3x 307

810:2x 3x 3x 3x 3x 5

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2x 3 = 12

Therefore, the value for common factors is 12.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 55713685926240/(1x12)

LCM = 55713685926240/12

LCM = 4642807160520

Thus, we can understand that the LCM of 248,578,521,921,810 is 4642807160520.
